Hi! I was wondering the same thing..
Instead of messing around to shift the color around manually and hoping to get it right, try this as a first step when doing your Primary color correction. Anyways here’s what to do in Final Cut Pro – pull up the color-corrector 3-way, go to the whites section. Click the little dropper on the bottom left of the circle and then go to your image and click on something that should be white. paper, a shirt, a sign, etc… and there you go, the color is white balanced.
It didn’t change the lighting of the scene, the color is still there.. But this is your first step and then changing the color of the light – I’m not sure how to do that yet.. hehe. However this white balance step really makes the image look much better and you may be fine to keep the color of the light in.
The only thing I can suggest right now without doing more research is that in color corrector 3-way, you turn up the opposite color in each of the Black, Mids (Gamma) and Highs, So a yellow/orange light you would add blue… it improves the image again and makes it more like white light but its still not perfect. I found on a test clip that I had to turn up the blue much higher on the whites than in the mids or blacks.
Primary is the first step you do to get the clips RGB In balance which I’m pretty sure is what white balancing is all about, making sure white is white, black is black and the colors are right and not shifted…
who am I? Perhaps I am a person who can record moving photographs with passion and zest! oh yes?
